    Ptolemy's Ancient Planetary Observations
    Annals of Science 63 (3): 255-290. 2006.
    Summary The Almagest of Ptolemy (mid-second century ad) contains eleven dated reports of observations of the positions of planets made during the third century bc in Babylon and Hellenistic Egypt. The present paper investigates the character, purpose, and conventions of the observational programmes from which these reports derive, the channels of their transmission to Ptolemy's time, and the fidelity of Ptolemy's presentation of them. Like the Babylonian observational programme, about which we h…Read more

    Testing the Empathy Theory of Dreaming: The Relationships Between Dream Sharing and Trait and State Empathy
    with Mark Blagrove, Sioned Hale, Julia Lockheart, Michelle Carr, and Katja Valli
    Frontiers in Psychology 10. 2019.
    In general, dreams are a novel but realistic simulation of waking social life, with a mixture of characters, motivations, scenarios, and positive and negative emotions. We propose that the sharing of dreams has an empathic effect on the dreamer and on significant others who hear and engage with the telling of the dream. Study 1 tests three correlations that are predicted by the theory of dream sharing and empathy: that trait empathy will be correlated with frequency of telling dreams to others, …Read more

    A Study of Babylonian Observations of Planets Near Normal Stars
    Archive for History of Exact Sciences 58 (6): 475-536. 2004.
    Abstract.The present paper is an attempt to describe the observational practices behind a large and homogeneous body of Babylonian observation reports involving planets and certain bright stars near the ecliptic (“Normal Stars”). The reports in question are the only precise positional observations of planets in the Babylonian texts, and while we do not know their original purpose, they may have had a part in the development of predictive models for planetary phenomena in the second half of the f…Read more
